Abstract
The present invention relates to a mobile PC to which an application for safety check and precise safety diagnosis of a building is applied. It checks a building used by many people such as an apartment, a department store, a school, and a factory to be inspected. Regular inspections of aging are of great importance. Therefore, the building information corresponding to the building, maintenance management data of the building to be inspected, and the field survey data obtained by examining the building site to be inspected are inputted and stored, and the stored data is stored in the management PC to check the building In addition to reducing the time and effort required for on-site inspections, the inspectors can use the inspectors for on-site inspections, simplify on-site inspections and reporting procedures, And a mobile PC-based device to which an application for precise safety diagnosis is applied.
Description
The present invention relates to a mobile PC-based device equipped with an app for reviewing and precisely diagnosing buildings, and more particularly relates to an apparatus and method for monitoring a building, Instead of handwriting the data acquired by field engineers on site inspection forms and handwritten drawings on the site, the inspectors use a safety check and precision diagnosis application on the tablet PC to input and store data, By automatically organizing the contents of the inspection service report, it is possible to improve the accuracy of the data compared to the current on-site inspection method in the drawings and to prevent the frequent occurrence of loss of survey data, To reduce the time required for rework by moving to the safety inspection and diagnostic work It can also contribute to the improvement of productivity and safety. It is also possible for the safety inspection technician to input the test data and structural calculation numerical values, ≪ / RTI >
Since the 1970s, Korea has devoted much efforts to the construction of buildings and residential apartments in order to lay the foundations for national reconstruction, industrial and economic development. However, buildings used by many people, such as apartments, department stores, schools, factories, etc., can cause collapse if there is no systematic check for obsolescence, and can cause confusion due to malfunction of facilities installed inside the building. Regular safety inspections of buildings are very important. In 1995, the Special Law on Facilities Safety Inspection (hereinafter referred to as the "Special Law") was enacted and implemented, and in 1999, safety inspection and precision safety Diagnostic guidelines are notified and are being used for inspection and diagnosis tasks. In addition, since 2008, safety inspection of small-scale vulnerable facilities has been reflected in the special law.
The safety check and precise diagnosis period of the building according to the above mentioned method is determined according to the size and condition of the building. After the qualified private inspection and diagnosis company conducts safety check, precision safety check and precision safety diagnosis, The results are reported to the industrial complex. However, most of the private safety inspection and precision safety diagnosis companies are very small, and Korea Facility Safety Corporation is not interested in investment that can improve the efficiency of the whole safety inspection process. And rewriting it at the time of report generation.
In the safety inspection and precision safety diagnosis of the present building, inspectors inscribe defects into paper checklists and drawings on paper in order to evaluate condition, safety, and comprehensive evaluation grade. And the material is tested. However, paper checklists and drawings are often inconvenient and dangerous to damage and impair the recorded data. Furthermore, when the above-mentioned appearance inspection is carried out, if the measurement result is inputted into the check list or drawing and left as a photograph, the work can not be efficiently performed when there is no auxiliary manpower.
Generally, the results of the inspection survey made by the manual at the safety inspection site of the building are re-inputted into the desk, so that it is time-consuming and troublesome to prepare the final report. In addition, if the checklist written by handwritten is lost or damaged, it may be dependent on the experience or memories of the person in charge, and subjective opinions of the person in charge may be reflected, and the result may vary depending on the degree of skill.
Therefore, we collect the building information of the building to be inspected, collect maintenance data of the target building, input the inspection data collected in the field by directly investigating the site, , And to improve the accuracy of the inspection.
The laws related to the safety inspection and diagnosis of buildings in Korea are largely 'special law for the safety management of buildings' and 'construction technology promotion law'. However, it has been pointed out that it is difficult to carry out efficient safety inspection and diagnosis work over the life cycle of buildings, because the laws and ordinances stipulating during construction, after completion and after construction are different. Therefore, since 2014, small- to medium-sized buildings are obliged to carry out safety inspections, but current safety inspections and precision safety diagnosis manuals are optimized for buildings 1 and 2.
Generally, in the safety inspection and precision safety diagnosis of buildings, the defects of the building are entered manually in the checklist for the state evaluation, the safety evaluation and the comprehensive evaluation grade, and the appearance and the strength An investigation should be conducted. However, when there are many checklist items made of paper, it is inconvenient to carry, it may be wet or torn due to water, which may damage the data recorded as damage and loss. In addition, when the appearance inspection is performed, the non-mass test, the steel exploration and the chloride measurement The biggest disadvantage is that it is not possible to perform tasks efficiently if there is no auxiliary manpower because the procedure of entering the results into the checklist and leaving them as photos is complicated.
On the other hand, although studies have been carried out to secure the quality of buildings and improve the efficiency of safety management, there are still cases in which the application is not practical from the viewpoint of practicality. As a result, there is a great need for the development of an app that makes it easy to write reports on site. Accordingly, an object of the present invention is to provide a safety inspection application for a building that can support the on-site work by hand by utilizing a tablet PC, etc. in order to increase the efficiency from the viewpoint of safety diagnosis and maintenance and to secure the reliability of survey data And to develop a mobile PC-based device.
On the other hand, the research on the domestic field inspection and maintenance study has been conducted, and the research on the app development supporting the construction site inspection and maintenance through the smart device has been carried out. However, the application based system for safety inspection and diagnosis of buildings, There have been no studies on apps that can support evaluation and status assessment.
Therefore, according to the present invention, a CAD-based drawing is converted into a JPG in a folder of the building to be inspected, then the user is connected to the application, a target building is selected, a layer to be inspected is selected, And a test / measurement value inputting a value of a material test result and an estimation strength after inputting a result of a material test, and a field test / A measurement function and an evaluation menu for selecting a layer to be evaluated, and evaluating appearance, which sequentially evaluates cracks, peeling, leakage, etc. of the evaluation target layer member selected in the evaluation menu selection step, Hardness, concrete carbonation, and corrosion of reinforcing steel after evaluation and evaluation, the appearance inspection and test measurement And evaluating the members for evaluating the member grade and evaluating the members by evaluating the members by evaluating the evaluation values of the appearance inspection evaluation step and the test measurement evaluation step, A safety evaluation function, an overall evaluation function, and a function of supporting a report generation.
The appearance inspection evaluation of the present invention is characterized by evaluating columns, bearing walls, large beams, small beams, and slabs.
Further, the state evaluation of the present invention is characterized in that it is possible to evaluate the state of the first and second buildings and all other small and medium-sized buildings.
In addition, the appearance inspection function of the present invention is characterized in that JPG format drawings are inserted in advance to display vertical cracks, horizontal cracks, cracks in sagging, cracks in the screen, leakage areas, etc. on the tablet in the field .
The present invention improves the problems of the safety check and the precision safety diagnosis and the conventional problems to improve the efficiency of the diagnosis work and secure the reliability of the surveyed data so that the safety inspection of buildings and buildings can be performed quickly .
1 is a view for explaining a safety check of a conventional building.
Fig. 2 is a diagram for explaining the efficiency enhancement of the safety check service through the smart device.
FIG. 3 is a view for explaining a function flow of a mobile PC-based device equipped with a building safety check and precision safety diagnosis app according to the present invention.
In the present invention, the scope of the study is limited to the safety inspection and the precision safety diagnosis of the 1,2 kinds of buildings and the small and medium size buildings during the construction, the construction before and after completion, and the strict safety diagnosis prescribed in the "special law" and "dry season method". For reference, the survey items for precise safety diagnosis from the viewpoint of life cycle before construction, before completion, after completion of construction, etc. are divided into visual inspection, basic survey and additional survey in "dry season method" Absence, durability, displacement, and deformation. The naked eye inspection of the dry method is a method of inspecting with a human eye, and it is a visual inspection of cracks, material separation, leakage, and occurrence of cold joints in the vicinity of a building. And investigating the displacement of structural members that can be easily measured, and examining the inspection items that were set when establishing the inspection plan. As a further investigation, the survey of the entire building structure is made and the geological survey such as drilling, prospecting, in-bay test, rock strength test is conducted, and the ground investigation and the ground investigation such as soil test and stratum analysis are carried out. Next, drilling of concrete, sampling of specimens, strength test, and physical property test are carried out. Then, the concrete material test to conduct the core sampling, the strength, the composition, the air amount, and the chloride content test is performed. Next, after the steel non-destructive test, installation and demolition of the construction material necessary for the investigation of the structure is carried out. Next, the bridge and the tunnel of the vehicle are checked for the investigation of the upper structure of the bridge and the investigation of the inside of the tunnel, and the non-destructive load test of the static and dynamic load test is performed. Then, if structural, ground, hydraulic analysis and structural stability evaluation are required, expert consultation and restoration and restoration of finishing materials are performed. Next, we survey and test electric and mechanical equipments, and measure and measure the earth pressure, displacement measurement, and measurement using instrumentation and instrumentation to understand the state and displacement of the structure. The next step is to carry out the investigations necessary to perform the checks effectively.
In addition, the safety inspection items of the 'special law' include structural stability, absence and durability, and displacement. In order to examine the deformation, first, the structural stability is checked by the member strength test to examine the strength of the main members such as columns, beams, bearing walls and slabs, and the concrete compression strength and member specifications, the reinforcement spacing, , The crack width and the area ratio are inspected. Next, the depth of progress of concrete carbonation is checked, and the corrosion condition of steel and corrosion environment are examined. In addition, surface deterioration tests such as peeling, thin film, and layer separation, leakage, leaching, and rebar exposure test are performed. Next, the content of chloride ions is checked, and finally the slope differential settlement is checked to check the slope of the structure and the slope of the structure due to the slope of the building and the floating settlement. As described above, in the conventional safety check, the safety diagnosis of the building is performed by the 'dry season method' and the 'special method'. However, the building safety check using the mobile PC based device using the app according to the present invention is described above It can be distinguished from conventional safety inspection.
The present invention will now be described in detail with reference to the drawings.
FIG. 1 is a view for explaining a conventional safety inspection method. As shown in FIG. 1, at least three persons are configured to divide duties such as measurement, recording, and photographing by a person so as to check a building or a building site. Next, the data recorded by manual operation such as measurement, recording, and photographing are rearranged and recorded, and the recorded data is re-entered. However, this conventional method is directly measured, recorded, and photographed by a person, which is a disadvantage in that there is a high possibility of omission of information, omission of recording, and recording error at the time of final report creation.
FIG. 2 is a diagram for explaining the efficiency enhancement of the safety inspection work through a smart device, in which a smart device is used to directly examine the appearance of a building or a building and input the result directly into the device, do. The appearance inspection method by the smart device can perform the status evaluation and the safety evaluation by shortening the convenience of the work and the working time with the minimum number of persons and the function of evaluating the grade in the device itself is installed, By sending the results, it is possible to improve the efficiency of report writing.
